SYSTEMS AND METHODS FOR IMPROVEMENTS IN TRAINING FIELD DESIGN FOR INCREASED SYMBOL DURATIONS Russian patent published in 2018 - IPC H04L25/02 

FIELD: communication equipment.

SUBSTANCE: invention relates to communication engineering and can be used in systems with training fields. Methods, devices and computer media for improving training field design in packets with increased symbol durations are disclosed. In one aspect, a method of transmitting a packet on a wireless communication network is disclosed. Method includes transmitting a preamble of the packet over one or more space-time-streams, the preamble including one or more training fields configured to be used for channel estimation, the one or more training fields each comprising one or more symbols of a first symbol duration. Method further includes transmitting a payload of the packet over the one or more space-time-streams, the payload comprising one or more symbols of a second symbol duration, the second symbol duration greater than the first symbol duration.

EFFECT: technical result is higher transmission capacity of transmission channels.
